The application as submitted includes no physical development of structures at the subject site. 3. Based upon the substantial evidence presented to the Planning Commission at the above -referenced public hearing meeting and upon the specific findings of facts set forth in Paragraphs 1, and 2 above stated, the Planning Commission hereby finds and concludes the following with respect to the Tentative Tract Map: a. The tentative tract map, design, and improvements are consistent with the General Plan and Development Code. The Project site is consistent with the Etiwanda Heights Neighborhood and Conservation Plan (EHNCP) Rural Sub -zone Development Standards for the Rural Hillside (H -R) zoning designation. The Project will create five (5) numbered lots for the future construction of single-family residential and will create six (6) letter lots proposed to remain as open space. The created lots meet the density of one (1) dwelling unit per two (2) acres and the building standards of the EHNCP. The Project is consistent with the Vision, Goals, and Principles of the EHNCP Rural Development Sub -Zone, including Goal No. 1: To permanently conserve and manage as rural open space the largest feasible portion of the Rural/Conservation Area and Goal No. 2: To ensure that all development and uses within the Rural/Conservation Area are aesthetically compatible with the rural foothill character and landscape. The subdivision is proposed as a clustered development, which supports residential uses while maintaining open space areas and boundaries from environmental constraints and preserving the natural character of the hillside rural area. Accordingly, the proposed tentative tract map, project design, and improvements are consistent with the H -R Sub -Zone designation of the EHNCP; and PLANNING COMMISSION RESOLUTION NO. 2026-009 TENTATIVE TRACT MAP No. SUBTT20653 DeCliff Properties LLC Page 4 b. The site is physically suitable for the proposed subdivision and for the proposed density. The tentative tract map proposes to subdivide two parcels totaling approximately 39.58 acres and create five (5) numbered lots ranging between 2 acres to 3.41 acres, for the future construction of single-family hillside residential and create six (6) letter lots proposed to remain as open space. The site is physically suitable for the proposed development and has been designed in compliance with the EHNCP standards, including but not limited to meeting the density, identifying environmental constraints, determining location of homesites, compliance with lot area, building setbacks, fuel modification buffer, and meeting universal standards keeping distance requirements from fault lines and Blue Line steam areas; and c. The design of the subdivision and proposed improvements are not likely to cause substantial environmental damage, avoidable injury to fish or wildlife or their habitat, or serious public health problems. The proposed subdivision and improvements are consistent with the development standards of the EHNCP. The proposed clustering design will avoid environmentally sensitive areas, such as fault lines, Blue Line Stream, and will avoid areas zoned Flood Control/Utility Corridor (R-FC/UC) and Open Space (R -OS). In addition, a CEQA compliance Memorandum was prepared pursuant to California Environmental Quality Act (CEQA) pursuant to State CEQA Guidelines Section 15183 finding the Project consistent with the EHNCP. d. The design of the tentative tract map will not conflict with any easements acquired by the public at large, for access through or use of property within the proposed subdivision. In this connection, the governing body may approve a map if it finds that alternate easements, for access or for use, will be provided, and that these will be substantially equivalent to ones previously acquired by the public. This shall apply only to easements of record or to easements established by judgment of a court of competent jurisdiction and no authority is hereby granted to a legislative body to determine that the public at large has acquired easements for access through or use of property within the proposed subdivision. The proposed subdivision main vehicular access will be via a 60 -foot dedication roadway share access agreement along DeCliff Drive. In addition, a sixty (60) foot wide shared access road dedication leading to the five (5) created lots will cross an existing sixty (60) foot dedication per parcel map No. 9461, located within the General Open Space and Facilities Los Angeles Department of Water and Power Easement through the General Open Space and Facilities. The Project has been conditioned to acquire the required access easements. 4. The approval of the Project is in compliance with the California Environmental Quality Act (CEQA). Pursuant to State CEQA Guidelines Section 15183 — Projects Consistent with a Community Plan, General Plan, or Zoning. Environmental impacts associated with development in the project area were previously analyzed in the Etiwanda Heights Neighborhood and Conservation Plan (EHNCP) certified Environmental Impact Report (EIR) adopted by the City Council in October 2019, (SCH No. 2017091027). A CEQA Compliance Memorandum was prepared pursuant to Section 15183 by Lilburn Corporation dated February 2026. The analysis concluded that: There are no project -specific significant impacts peculiar to the site that were not analyzed in the EHNCP EIR; PLANNING COMMISSION RESOLUTION NO. 2026-009 TENTATIVE TRACT MAP No. SUBTT20653 DeCliff Properties LLC Page 5 b. There are no significant impacts not previously analyzed in the EHNCP EIR; c. There are no significant off -site or cumulative impacts unaddressed by the EHNCP EIR; d. No new substantial information indicates that any previously identified impact is more severe than previously disclosed. All potential impacts have either been analyzed in the EHNCP EIR or can be mitigated to a less -than - significant level by existing development standards and no further environmental review is required under CEQA Guidelines Section 15183. 5. Based upon the findings and conclusions set forth in Paragraphs 1, 2, 3, and 4 above, the Planning Commission hereby approves the application for Tentative Tract Map No. SUBTT20653 subject to each and every condition set forth in the Conditions of Approval, attached hereto and incorporated herein by this reference. 6.
